Privacy Policy

Format conversion, encoding conversion, sync adjustment, search/replace, time range extraction, and file merging are processed entirely in your browser. No subtitle files are transmitted to or collected by any external server during this process.

Blu-ray PGS (SUP) OCR subtitle extraction and translation features use server communication. Uploaded files and translation text are immediately deleted from the server upon completion and are not stored separately.

SubTrans does not use cookies. Only theme settings (dark/light mode) and OCR language selection are stored in your browser's localStorage. This data is never transmitted externally.

Web fonts are loaded from Google Fonts (fonts.googleapis.com) for page rendering. Your IP address may be transmitted to Google during this process. For details, see the Google Privacy Policy.
